2/7x+1/2x=40/7-1/6x solve for x

Mathematics
1 answer:
torisob [31]3 years ago

Answer:

Keeping in mind the 'x' is in numerator, i got the answer to be 6.

Step-by-step explanation:

2/7x + 1/2x = 40/7 - 1/6x

2/7x + 1/2x + 1/6x = 40/7

2/7x + (3+1)/6x = 40/7

2/7x + 4/6x = 40/7

2/7x + 2/3x = 40/7

(2*3)+(2*7) / (7*3)x = 40/7

(6+14) / 21x = 40/7

20/21x = 40/7

20x = 40*21/7

20x = 40*3

x = 40*3 /20

x = 2*3

x=6

The length of a rectangle is 2 meters more than its width. The area of the rectangle is 80 square meters. What is the length and
insens350 [35]

Answer:

Step-by-step explanation:

Formula

A = L * W

Givens

W = W

L = W + 2

Solution

Area = L*W

Area = (W+2)*W = 80            Remove the brackets.

Area = W^2 + 2W = 80         Subtract 80 from both sides.

Area = w^2+2W-80=80-80  Combine

Area = w^2 +2W-80 = 0        Factor.

Area = (w+10)(w - 8) = 0

W + 10 = 0 won't work

W = - 10 which isn't possible

W- 8 = 0

W = 8

L = 8 + 2 = 10

The answer looks like A
